TRUCK SIDE BEARING Specification of Letters '.Patent.

Patented May 8, 1906.

.To ttt whom/t may concern:

Be it known that we, CARL E. BAUER and FRANK L. SUSEMIHL, citizens ofthe United States, residing at Hammond, in the State oiV Indiana, haveinvented certain new and useful Improvements in Truck Side Bearings, ofwhich the following is a specification,

Our invention relates to trucks for railway cars and thel like, and tothe bearings provided between the car holster and the truck near theoutside. 'ljhe principal objects are, to provide a superior roller'bearing for such position, to provide convenient means for renewing thebearing plates for such rollers and a convenient design of casing forreadily puttin together and taking apart, and to genera ly -improve thestructure land o eration of railway truck side bearings. hese objects,and other advantages which will hereinafter appear, we attain hy meansof the construction illustrated in preferred form in the accompanyingdrawings, wherein- Figure 1 is a top plan view of the assembled hearingcasing g Figure 2 1s an underplan view of the cover of the casing;

Figure 3 is a plan View of the lower naif of the casing with the bearingrollers removed;

Figures 4 and 5 are horizontal sections taken on the lines (4) and (5)in Figure S;

Figure 6 is a horizontal section similar to that 1n Figure 5, with thebearing rolls in a different position;

Fi ure 7 is a vertical section, taken along the line (7) in Figure 1 yFi re 8 is a cross section, taken along the line 58u) of Figure 1; and

' Figure 9 is a central vertical section taken along line (9) of Figure1.

The casing is made in two parts as especially shown in Figures 1, 2 and3, the lower or base portion 10 being provided with lugs 11 forattachment to the truck bolster and the upper portion 12 havingdepending flanges 12'a and 12b which engage the ledges l0 on Athe baseportion, and also having guide flanges 13 for the accommodation of thebody bolster thereon. Each of these arts, referaol made of malleafrlecastings, has a caring p ate, 14, 15, of steel which is set in as shownin Figures 7 and 8 A the edges ofthe plete being formed of dove-tail shae and the `plate secured by bending over t e edges 1 6 and 16a of thecasing to hold them in lace. Y Y,

he hearing proper is composed of a series of rolls 17 which run by meansof trunnons 18, slipped into the open slots 1S of the traveling frame1Q, are held in proper relative position to each other and travel alongthe bearing plates. Near the center of this frame 19 is an o ening 2()in which rides loosely a pin 21 having an openin therethrough as showninthe sections of 1gures 6 and 7, in which are placed two uide bars 22 and23 having respectively the earing studs 22 and 23a working in o enings24 in the lower casing 10 and a soc et formed in the upper casing (asshown in Figures 8 and 9) by means of the two extended webs 25 which areformed inte ral with the cover 12. The head 23 is retained therein bymeans of pin 27 held in the two openings 26.

AThe two bars 22 and 23 slide freely upon each other and also in theopening of pin` 21. The bars su port the pin 21 in the frameV 19, andallow o1P travel of the frame as the rollers traverse the late 15 ineither direction, hut cause the rollers to wear over the same distanceson both plates, and limit the movement at the extreme positions as shownin Figure 6, by coming in contact with part of the casin i9..

From t ls construction it will be seen that the assemblage ofthe vpartsis rendered very easy. The rollers having been put in place on thebearing plate 15, the pin 21 is put in place in the traveling frame 19and then the bar 22 is thrust through the `opening therein, when thehead 22 is placed in its socket 24 and the entire upper shell and theVtraveling frame 19 is set down over the rolls and other parts, theslots 18 en aging the tru'nnions 18 of the rollers 17 and tgli the lowercasing, engaging t e outer ledges 10 on the lower casing 10, as'wiii beunderstood. The top bar 23 ma now he slid into place and retainedtherein y the lpin 27 engaging the opening 26. It will be seen that wehave designed the form of the casing and of the rollers so as to make aperfect bearing in a circumference about the center of the e flan es 12slide over ICO truck, and the traveling frame and the roller 17 are freeto move the saine distances on the two bearings in either directionuntil limited by the stop bars 2.2 and 23. Both the bear- `be replacedat bolts to put the bearing together and all the parts are readilyremovable and renewable. Other advantages will readily occur to thosefamiliar with the art.

Having thus describedr our invention and illustrated its use,wl1at weclaim as new, and desire to secure by Letters Patent, is the followin y1'. il a truck bearing in combination, an upper bearing member providedwith upstanding brackets to loosely engage the car bolster, a lowerbearing member provided with means for positively securing it to a carmember, interlocking means on the two bearing members adapted to permita sliding 4motion and to prevent a relative vertical movement of suchmembers, and rollers interposed between the members.

2. In combination in a truck bearing, a casing comprising a lowerbearing member provided wlth means for fixing it on a truck and an upperbearing member slidingly attached thereto and provided with means forloosel engaging a car bolster, and rollers m- 4close in said casing.

3. In a truck bearing in combination, a casing composed of two slidablyattached parts, one part fixed on the truck and one part looselyengaging the car bolster, a set of rollers carried between and engagingsaid casing parts means for limiting the travel ol the parts of thecasing, and means for bolding the parts of the casing together.

4. In combination in a truck bearing, rollers, and an inclosedcasing'therefor, said casing composed of two parts slidable on oneanother and confined together and one of said parts having side bracketsto loosely engage and seat the car bolster, whereby the whole bearin maybe carried on the truck or bolster and 1s readily removable from thecorresponding member.

In testimony whereof we have hereunder sigbned our names in the presenceof the two su scribed witnesses.
